## Decision: Redux Toolkit 2.x
|
|
|
|
**Score**: 9.2/10
|
|
|
|
### Key Advantages
|
|
|
|
1. **Best for Complex State**
|
|
- Family structure, multi-person profiles, permissions
|
|
- Built-in normalization (createEntityAdapter)
|
|
- Predictable state updates
|
|
- Time-travel debugging
|
|
|
|
2. **Best for Offline Sync**
|
|
- RTK Query for server state management
|
|
- Optimistic updates
|
|
- Background sync support
|
|
- Battle-tested offline patterns
|
|
|
|
3. **Best Ecosystem**
|
|
- Largest ecosystem
|
|
- Most resources, tutorials, examples
|
|
- Most production deployments
|
|
- Easiest to hire developers
|
|
|
|
4. **Best Developer Experience**
|
|
- Time-travel debugging
|
|
- Predictable state updates
|
|
- Easy to debug
|
|
|
|
### Trade-offs
|
|
|
|
- More boilerplate: More code, but clearer structure
|
|
- Steeper learning curve: More concepts, but better patterns
|
|
- Larger bundle: 60KB vs 3KB (negligible impact on 50-100MB app)
|

## Technology Stack
|
|
|
|
### Shared (Monorepo)
|
|
- **State Management**: Redux Toolkit 2.x
|
|
- **Data Fetching**: RTK Query 2.x
|
|
- **Async Thunks**: createAsyncThunk
|
|
- **Persistence**: Redux Persist 6.x
|
|
- **Selectors**: Reselect 5.x
|
|
- **DevTools**: Redux DevTools
|

## Alternative Considered: Zustand
|
|
|
|
**Score**: 8.6/10
|
|
|
|
**Why Redux Toolkit wins**:
|
|
- Better for complex state (family structure)
|
|
- Better for offline sync (RTK Query)
|
|
- Larger ecosystem (more resources)
|
|
|
|
**When to use Zustand instead**:
|
|
- If team has no Redux experience
|
|
- If state is simpler (no family structure)
|
|
- If development speed is more important
|

## Next Steps
|
|
|
|
1. Implement Redux Toolkit POC
|
|
2. Create family structure state slice
|
|
3. Implement RTK Query for server state
|
|
4. Test offline synchronization
|
|
5. Test encrypted data caching
|
|
6. Make final decision
